Hello! My AO Smith ECT80 210 unit itself keeps tripping. Almost daily I have to push the red button on the controller to start it up again. I've double checked the connections and they all seem good. I even slightly tightened one. I also lowered the temperature, which seemed to have been hotter too, but that could've been my imagination ;) The unit is just past its 6 year warranty of course. Worth trying to install new controller or can adjustments be made? Or do I just need a new water heater? Thanks in advance for any advice!

Hi,

I have run into this many times, you'll need to replace that upper thermostat to fix this problem.

Ok, sounds good, keep us posted.

Make sure you turn the breaker off to the water heater before you begin.
